Best home server OS?

I just got a new-ish computer, and set my old one in the closet. I was looking around for things to do with it, and I basically decided to use it as a home server. Ill use it to FTP files, stream music and Video, and possibly host a web page, who knows.

so Im looking for the best OS to use. I have no Linux history, so I basically got it down to Windows XP or 2000, but if someone could point me to a guide for a headless Linux server site guide thingger, that can do all I said about I would greatly appreciate it, as I have many copy%26#039;s of Ubuntu stashed on my computer.

umm idk what more info you want but I current would have 3 desk-tops, and 2 laptops hooked to it, and possibly a small group of computers for gaming once in awhile.

Like I said, I want it to be headless (no monitor needed) just push the on button and its working (or just stays on for days and days)
